DEFEATED By My 39 Year Old BMW E30

- Finally back with an update. Didn't feel that I could get one out to you all without getting this high idle issue resolved, yet here we are.
This episode we get rid of the ICV delete on my 1984 BMW 318i with the M10 engine. I get the throttle body back to factory spec, and reinstall the Idle Control Valve.
We then tested out a new/used Idle Control Valve, and we shotgunned in a new/used Idle Control Module.
The car is driving great, but this high idle is preventing me from smogging it here in California :/
Hard to believe CA still wants me to smog a 40 year old car...
Anywho, we made some good progress! This is where the road ends for me and this E30.
More details will follow at the end of the video, but I have my sights set elsewhere at the moment.
I hope you find this video helpful!

Have you contacted m539 Sreten ?
i havent, figured i wouldnt get through via email, but ill give it a shot!
Once again M539 Restorations Is the Best Thing on UA-cam Right Now - Road & Track. This guy knows so much about restoration of BMWs. He's the key to getting the diagnosis . He's a nice guy in Frankfort Germany and I emailed him as well!! Why? Because I had 2 2002 BMWs in mid 1970 to -1983
Good to see you again Glenn. Ill have to reach out, ive seen a bit of his content, but didnt think of emailing him, i didnt expect to receive a reply. Ill give it a shot though, cant hurt. I do have some tester parts on the way so im a bit more hopeful
I was about to type this exact comment. @DayOffDIY, I believe he has some content you can refer to for your E39. He probably knows why this idle issue is happening. Best of luck!
I can only imagine how frustrating this issue is.. Hope the new project will be smooth sailing. I'm excited for it!
Frustrating no doubt. I’m pretty bummed I wasn’t able to tackle it, but this next video is going to make up for it no doubt
yes you will!@@DayOffDIY
@@DayOffDIYI have no doubt whatsoever!
This is very interesting. Because every BMW I’ve owned had random RPM cold starts. Some high. Most normal.
this is new for me! I prefer OBD2 systems, but i am learning a lot
I just purchased a 1984 BMW 318i with the M10 for $800 about 3 weeks ago. She was in rough condition, I hired a tow truck to come rip her from the ground and haul her to my garage. I have always done my own basic maintenance on my daily drivers but I've never taken on a project car. Do you have a community online anywhere other than your UA-cam channel? You should consider making a discord or something. Thank you so much for putting out these videos because I've already learned so much about this car through your channel.
congratulations on your new project! sounds like you got a score. same car!
I do not have a discord but youve inspired me to get one made! Ill be sure to announce it when I do, it would be awesome to have a place for us to share knowledge
Alec, your channel has some of the most interesting but frustrating content out there! Boy are you lucky.
Hahahah this car is frustrating that’s for sure, sounds like decent content from your description. Cant wait to get this project revealed to you guys
You and Ray are the Best ever 😊
thanks friend!
If I had the cash on hand, I would. The E30 is a beautiful BMW and I'd love to take on that project. Good luck with it!
hoping theres a good owner out there for it somewhere! appreciate the support friend!
Hey man, that issue must be driving you insane! You'll be able to sleep so much better when it is gone 😂 I can't wait to see what the next project is, praying for an E39 but would love to see an E60 too. Take care man!
I agree, any E chassis 5 series would be sick!
@@ricardogomez9712 for sure, some cool engine options!
I agree, id love to work on an E39 or an E60!
Thanks for the support Ross, it really has been driving me crazy, wasnt proud to put an update out and not have it running tip top yet, but thats the way it goes!
I need to show the good, bad, and the ugly.
This next project will no doubt blow some socks off. Guaranteed
Enjoyed your content and those hopeless old wonderful early 3 series, so I tuned into your channel. Will have to return when I develop the natural interest in newer vehicles - hopefully your project is also a bmw - there is an interested viewership that will suffer though delays and challenges, it's a vicarious thrill and an education. The challenge of a motorsport is the working through the impossible. This is a great challenge. Some have to see the perfect future - passing emissions. There is also a giant body of knowledge on the internet and on beemer forums. Many will show photos, direct you to information, or having faced the issue successfully are more than will to share there triumphs to the same issue you are facing.
I apologize but this video of yours, as you worked through the issues at 9:50 minutes, your tone of voice carried a certain resignation - you were no longer envisioning yourself cruising it your amazing cool amazing deal fun BMW. So it won't pass smog for an emissions issue, the question is, has any 984 BMW 318i passed smog in this current time? I will watch again listening for fix details. Did you change O2 sensor (check for resistivity of sensor from the wiring), pressure control valve (positive vacuum in the crankcase). Did you use a small metal tube attached to a garden hose to listen for vacuum leaks, or use those smoke (mineral oil vapors) device - maybe at auto parts stores - to look for vacuum leaks. Coolant sensors? Enjoy your 318i challenge.
Hey Curt thanks for the comment! I agree, the best triumph comes at the other side of the struggle.
I will no doubt remain a primarily BMW channel, and future projects will mostly be BMW.
Ive also done a lot of digging on the forums but havent found the solution yet.
I agree, i was quite beaten down by this one, and I have lost the vision of cruising around in this car, but if I can find a resolution for it maybe ill get it back.
havent changed the 02 sensor yet but i have one on the way, as well as a AFM to test.
Ive checked for vacuum leaks and have smoke tested the engine and intake.
Thanks for the support and the comment!
Man I would’ve gave up a long time before you did, your persistence is admirable. Onto bigger and better things from here🙏
im trying to keep my spirits up so i can bring you guys some more content, but yeah this one beat me down. Im feeling a bit more hopeful now, @robsweekendgarage is shipping me some parts to test on it thankfully.
maybe one more video trying to get it fixed!
@@DayOffDIY hell yeah, give it one last go
I bought the same exact year make and model for the same price!
I’m pretty much plan on following everything you do with the car to do to mine
awesome! I hope repairs go smooth!!!
My E36 does this sometimes. Sometimes it will start at 2K RPM like there's a vacuum leak. Usually though it's good. I deleted that whole vacuum pump / muffler flap system and there are no leaks. The cats are suspect, but today I think it might be electrical / connector related. The wiring isn't in the best of shape and I've had a couple plug / connection problems elsewhere.
Whats up Liam!
Yeah its been a real headache. Feeling a lot more hopeful about it though, @robsweekendgarage is shipping me out some components that i can test on it so hopefully we can find a solution that doesnt cost me another $1,000 lol
i do still really wanna sell it though.
more modern OBD2 cars are my cup of tea.
good to see you as always!
Well it’s not for a lack of trying Alec. You have a great knack of methodical diagnosis. If there are any m10 things you may want to parts cannon at it lmk as I have mine for sale. Cheap/free!
Looking forward to the next vid!
Thanks Rob, I’m still not too pumped on it, it hurt to post this video, I feel like I lost the battle, but this next video is going to be legendary.
Not even sure what we could throw at it next, temp sensor, or the computer? What do you think? I feel like I’ve tried most, besides those and the air sensor
@@DayOffDIYremember, Edison didn’t fail 1000 times to invent the light bulb - he found a 1000 ways to not build a light bulb lol.
Yah I can send any of those things. I can’t guarantee any of them will work but you’re free to try them out.
Hello, Check the wire temp sensor in the stand wire 😒😉
i definitely will
What an annoying issue man! I hate those weird ones that are intermittent. I work in I.T, so while it's different to cars, the same thought process applies when it comes to troubleshooting and I know that it would be doing my head in if this was a computer I was trying to fix. I reckon sell that baby and forget about it lol.
Whats up Liam!
you totally understand, this one has been a real headache, but ive no doubt learned a lot!
Im feeling more hopeful though, one of my viewers @robsweekendgarage is shipping me out a bunch of parts to test with, so im super pumped and grateful for that. hoping i can find a resolution soon, although i still do want to sell it.
I prefer the newer obd2 cars personally. its what i was brought up on
Good to see you Liam!!!
Good video
Glad you enjoyed
my 88 E30 325is had the same exact symptoms. it ended up being the Air Flow Meter. I found someone parting a car out and was able to buy the complete intake box and ICV for $50
thanks to your comment i got a used AFM on the way, with some other components, thanks to one of our viewers @robsweekendgarage
@@DayOffDIY that’s great to hear! I hope it’s the problem. I have been posting my e30 journey to my channel too, idling issues and rust repair! I hope you solve the issue. If you do decide to sell at least you can say you solved the mystery!
dude I just took a look at your channel, your videos are awesome! Getting down on that E30. Thanks for the comment Zack! I just subbed
@@DayOffDIY I appreciate the love!
Alec i just want to add that with the economy the way it is maybe with bring a trailer and see what people are willing to trade for it. I've been messing with cars for 40 years now and I can say that sometimes what people can't afford to pay they can afford to trade. Who knows everything from boating to a future car for the channel! Anyway good luck and God bless!
Great idea johnny! I think i got another few weeks in me to see if i can get it fixed. One of my viewers that goes by @robsweekendgarage is shipping me out some parts to test so im feeling much more hopeful! its just getting expensive fast. when you see my next project youll have a better idea why :)
Just like some of the others mentioned, sreten from the channel M539 Restorations will more than likely be able to help you, super knowledgeable BMW guy!
Good call Andy, I just figured I wouldnt get a reply if i reached out via email. I guess it wouldnt hurt to try! going to watch his E30 videos today
🔥🔥🔥🔥
Gunnar! Miss you brother!
So frustrating. I hope you'll encounter the answer to the issue. Sometimes it's best just to leave it and the solution will come to you one day, but that's not really doable with the space a complete car takes of course.
thanks for the comment! Time definitely helps, luckily one of my viewers @robsweekendgarage is shipping me out some components to test, see if we cant find a solution here. Gotta love the little community we are building
Old BMW and Mercedes vehicles have 2 coolant temp sensors. One is for the temp gauge. The other is for the fuel injection idle control valve. The idle control module gets its signal from the other temp sensor to control the voltage to the idle control valve. A quick test is to start the car cold. Let it idle. Pull off electrical connector to ICV and see if idle increases. Measure voltage at the connector with car cold and idling , then measure it with engine warm. It should be a different Voltage. Find that other temp sensor and check with ohmmeter cold and then at operating temp. Specs should be online.
good tip my friend! still getting used to this older style fuel injection. Im gearing up to get back to work on the E30 today and tomorrow so ill try to look into it some more.
I had the same problem with ny e30 its the same with m10 engine.
And thw mass air flow was set to rich.
You need to open the airmass and try it with landba sonda or with your ear to set it correct with fuel and air and then try to mess with everything else.
I hope it helps
i got a spare air mass sensor so ill have to tinker on it this week!
Try replace throttle body, maybe shaft on that throttle body is worn and have such play for vaccum/air leak into engine
Try spray some brake cleaner on seals, on that throttle body, everywhere and when you have some leak, you will hear iddle going up or stall.
Sorry for bad language i'm still learning (greetings from Slovakia)
Slovakia! awesome. Ive smoke tested it to check for vacuum leaks, and none were found, besides a small wisp at the throttle body linkage, however i think its too small to cause a vacuum leak type issue.
That E30 engine looks simple. I thought it would be easier to work on than the N52 motor...🤔
It’s simpler but also this fuel injection sucksssss!
You need to change the temperature sensor.
I had this on my mk2 golf gti. Me and my dad had identical white and red ones. His ran sweet, mine always was up and down. Purely by luck I sucked on a pipe that lead out near the same idle valve that ran out of the aluminium cast piece next to it. We took it off and the hole was blanked off, like it had forgetten to be drilled out in production. Stuck a drill down it, reassembled and problem gone. Maybe that it in a similar way?
wow what a crazy story! just some small little detail that was forgotten at the factory. Very well could be a similar issue! got some replacement parts on the way so i will try again
IIRC M539 Restorations went through the same thing with his own E30.
according to you guys it sounds like it ! Im going to give his e30 videos a watch today
I was frustrated just watching the video so God knows how you feel!!
appreciate it luke! we will keep trying!
Hey Alec, have you tested the gap all around the throttle body butterfly when the engine is idling? It must be getting air from somewhere to idle so high. Just a thought mate!
the gap is all good on the TB, i smoked it too but it is only leaking a small little wisp where the rod for the throttle body goes into the housing. should be giving this car another go this evening and into tomorrow. hopefully we make some progress!
Uszczelka pod głowicą albo rozrząd źle ustawiony.
it has great compression, and this engine is ran off of timing chain.
@@DayOffDIY to że ma dobrą kompresję nie znaczy że uszczelka jest dobra bo może być micro pęknięcie między cylindrami i kompresja będzie przechodziła z cylindera do cylindra. Sprawdź szczelność cylindrów.
Alright man. So I have really tried to tackle my 84 318i w/ the m10b18 same as yours ever since finding your channel.
A little update. I’ve - deleted ICV. Deleted cold start injector. Replaced injectors. Fuel filter. Did full leak down (found VCG leak, vacuum canister leak, ICV delete leaking). Fixed ALL leaks - that has been major. New Bosch plus, wires, cap + rotor. Did timing adjustment. 4-1 headers repairing exhaust leaks and deleting ancient cat. Valve adjustment to factory specs (.006-.008). New radiator. Thermostat. Alternator.
Man, I’m in the SAME boat as you. It runs WAY better. ICV and cold start injector is useless.
Mine is idling around 1300rpms and is solid for 2 minutes or so until it develops a small misfire that progressively gets worse.
I believe your idle going up then down randomly is because it’s detecting a misfire and correcting by raising idle.
I can get my idle much lower by adjusting the throttle adjustment screw but then it will eventually misfire.
At this point I don’t know what else I can do. Temp sensors (there’s two sensors next to the diagnosis connector)? Intake box/MAF thingy?
david I feel your pain!
This m10 can be real headache. It sounds like youve really covered the bases. Have you played around with the throttle position sensor yet? it needs to be calibrated to the throttle body position if youve messed with the throttle stop screw.
As far as where to go from here, Im waiting on a replacement Air Flow Meter from my awesome viewer/friend @robsweekendgarage. He has some parts hes sending over that I can test with.
I found this write up on this dudes personal website, give it a read, theres a ton of good info in here for what you and I are going through
@@DayOffDIY I have not messed with the throttle position sensor at all. I saw it was marked with yellow paint and figured I probably shouldn’t touch it! Lol. But I can give it a try. How exactly would I calibrate it? I saw in your video you did. But I was confused what pins you were taking readings from as well as “how” exactly. Also looks like a difficult space to test it and make adjustments in such a confined area. Just all around not super comfortable with a multimeter. But I understand it’s an important aspect to fixing/diag on vehicles.
Yesterday/today I actually seafoamed the engine (not knowing how long the vacuum leaks were there, figured maybe intake valves are gummed up), cleaned the plugs, bore scoped the cylinders, re- gaped the plugs to .030 and REALLY dialed in my ignition timing. Runs smoother for sure. But still misfires at idle if it sits for more than 60 seconds and has massive loss of power above 4500-5000rpms…
About ready to throw in the towel…
@@DayOffDIY and wow major perks of having a UA-cam channel!! Lol I’m super jealous! One day I’ll start recording all my car shenanigans! I also just picked up an e36 M3. Not sure what I want to do to that but that’ll be a fun one! Still need to install a lift on my XJ keep and don’t get me started on my plans for my 997 Turbo!😭
But this damn e30!! As terrible as it sounds, I laugh about it and am kind of glad I’m not the only one in this situation😭😂🤦🏽♂️
Hopefully one of us figures it out and reports back!!
Just a side note I’ve noticed every time you started the car with high idle the temp gauge didn’t move at all as in it wasn’t registering but when it idles normally it ping and went down probably not related just noticed have you checked the dme on the car the relays like to go also because the clocks stopped working on the car it’s hard to accept the dash reading
yeah i think there may be an issue there, luckily my friend rob hooked me up with a spare DME so ill be doing some testing the next couple days. been laser focused on my new build and have been neglecting this car too much
Let's make it roadworthy - classic BMW e30 320i 5-speed - project marbais: part 5
That's the name of the video where m539 restorations has a problem with sticking distributor body was causing high and surging revs
I tried posting a link but I guess it thought I was a spammer
Youre a legend! thanks for the link, im going to give it a watch today. never knew that streten went through the same struggles as me. A lot of you guys mentioned i should reach out to him but just figured i wouldnt be able to get a reply. might as well give it a try! thanks again
Would the cable itself be the issue? Stretched out due to age or replaced with a wrong part number at some time. Can't think of anything else that you haven't put hands on.
The cable is properly slack, I’ve checked it at the throttle body many times, However, I have more parts to test thanks to @robsweekendgarage so there will be another episode In the future 👍🏻
Alec I'm going to give my opinion on the e30, I think it's the catalytic converters on the car. Anyway on with the next project I personally am excited to see! I personally want to see your views sky high! You've already proved your capabilities on that subject. I am so excited for the future of your channel!!
I ought to take a look at the cat with a boroscope. very well could be the issue. its aftermarket, and its potentially old or clogged.
Thanks for all the kind words as always, cant wait to share the next project with you! shoot me an email when you get a chance!
Damn, feel sry for you, tried so hard to fix these thing properly
I still got a little more juice in the tank to keep going, thanks to this kickass community!
you're pretty close to me. i'm in reno. i have a sedan with an m10 if you want it....
tempting! Im thinking about moving towards a newer platform to work on, or id buy it just for interchanging parts! id say im about 6 hours or so from you. due west all the way to the coast
Throttle position sensor
I thought so too, but I have it adjusted within specification.
Do you have the previous owner title?
Do you ever try play with the distributor?
i have many times, replaced the vacuum advance, replaced the distributor, and have timed it multiple times. I got some ideas though!
What’s the elevation of where you’re at?
like 100 ft above sea level
Hoping the new car is a 335i
could be!
I definitely know the colour of your next project car but can I guess and mention the model in the comments?
you can try! but i cannot confirm nor deny :)
@@DayOffDIY E92 335i can’t wait until you reveal it.
told u 250$ and ill handle it 😂😂
lol add 5k to that and come take it from me lol
E60??
could be!
m50 swap
i didnt know i could legally do a m50 swap here in CA, but apparently you can if you get the BAR sticker, either way, my sights are set on my next project... however! I will be spending a little more time on the E30, got some replacement parts on the way to test
@@DayOffDIY i'm just messing with you, you'll get it, i'm sure!
Bro, $6000 is way too high.
A rusty automatic M10 car is worth $1000.
Ive had offers up to $4400.
Its worth far more than $1000, also depends on what the market is locally
Bring a trailer is a huge waste of time
you think? i know one person whos purchased off of it, had a good experience.
